Someone asked if PiOmxTextures (library and Qt OpenMAX-based multimedia plugin) could be used on Raspberry Pi 2 and if it could be used to play more than one video contemporarily. I worked on this and a couple of recent patches made the following result possible.

The video shows two videos running contemporarily on Pi 2, with QML animations applied to the videos and with audio fading from one to the other. The videos are 720p h264 main and high profile. UI is written in QML in 1080p with 24 bit color depth. As you can see, load on the CPU is very low. The demo also shows the same QML file running on Mac OS X.

To get this performance you'll need to properly overclock your Pi 2, otherwise the achievable frame rate is lower.
